Two things I noticed that could use improvement: I don't know if it's a shield mesh on the spacedock, or if large-ship bubble shields still don't work well, but those shield hits just looked awful. Also, I think the phaser beams are emitting too much light, and it's too red. I know phaser color varies by episode, and we can have a whole thread arguing over what precise shade of orange it ought to be, but the example I'm using is this:
http://www.youtube.com/watch?v=MCm70favfYI&t=1m45sYou can see that the Galaxy's beams make a faint reflection on its shiny hull, but they don't light up the whole ship. Pulse weapons and torpedoes can get away with lighting up the whole ship, because they move so quickly that you won't see the light at all if it isn't substantial. See the klingon disruptors at about 2:30 in that same video.
Otherwise, looks good so far. I mean, aside from the problems inherent in allowing beam-free-all on any Star Trek ship, namely that they'll fire all their beams at once, which they never do on the show.
